I assume you're using NOX destiny or zaku (these are the two current branches
of NOX). These branches now use a meta.json file to describe components. The
spanning tree component was written for an older version of NOX that used a
meta.xml file.
As far as I can remember, the spanning tree component still works fine -- you
just need to convert the meta file. The nox-convert-meta.py script (in
src/scripts) is meant for doing this. You can run it yourself, but I have
attached its output here as well.
So put the meta.json in the spanning tree directory, and modify Makefile.am to
refer to meta.json instead of meta.xml. Then run boot.sh, configure, and make
again... hopefully that'll do it! (As a shortcut, you could try just putting
meta.json in the spanning_tree directory in your build tree. I think that'll
work too.)
As a sidenote: you mention setting up an STP network, but the spanning tree
component *does not* implement STP. It creates a spanning tree entirely
within the controller and the switches by using OpenFlow.
Hope this helps.
